The role of hybridization in generating species- and population-level diversity in Sarracenia.

Sarracenia is genus of rhizomatous, perennial herbs centered in the southeastern United States with one species extending into New England and Canada. They are primarily found in sphagnous bogs, mountain seeps, and longleaf pine savannas. The group has long been popular in cultivation due both to their beauty and their carnivorous habit. Nearly all geographically-possible hybrids have been found in nature, as well as many complex hybrids in cultivation. However, the extent of natural hybridization and its role in generating morphological diversity in the group remains largely unknown. Our study uses a combination of non-coding chloroplast regions and nuclear gene regions to examine patterns of diversity and relationships within the genus.
